PMT Water movement

• What does water enter through?

  Root hair cells

  • and then moves into the xylem tissue located in the centre of the root.
  • This movement occurs as a result of a water potential gradient
  • as the water potential is higher inside the soil than inside the root hair cells
  • due to the dissolved substances in the cell sap.
• What is the purpose of root hair cells

  To provide a large surface area for the movement of water to occur
• How are minerals absorbed through the root hair cells?

  By active transport, as they need to be pumped against the concentration gradient
